Easy to install and use but the only reasonable choice among the 16 tunes was the default 2-note chime, and to this was appended a silly "hello". The other 15 tunes were way too long for a simple household doorbell requirement. The chime itself (and the other tunes too) sounded somewhat distorted and unpleasant.

This doorbell is perfect. It can be heard very clearly & you can take it to any room of your house & if you move you can take it with you. I would recommend it to anyone who wanted to have a doorbell, especially if you can do it yourself without calling an electrician.
